What is inside
The template opens in Microsoft Word, Google Docs and LibreOffice. It already contains every detail required of a supporting document in Latvia: invoice number and date, supplier and customer blocks with registration and VAT numbers, an 8-row line table, subtotal, VAT and total, the amount in words, bank details and payment term.
If you are not VAT-registered
Delete the VAT row entirely rather than writing "VAT 0%" — the zero rate means something else. Add a note that the supplier is not in the VAT payer register. See invoice without VAT.
The weakness of a Word template
Every next invoice has to be rewritten by hand — number, VAT, amount in words — which is where duplicate invoice numbers and mismatched VAT come from. If you invoice more than once a month, the invoice generator is faster, or take the Excel template if you want formulas.
